We have a full size IKEA bed for sale, $120 OBO.
The bed is a platform bed (about 55" x 77"), with a typical IKEA slatted bed base, and 8" clearance underneath.

The mattress is about one year old, and is a 10" thick Signature Sleep Contour Reversible Encased Coil mattress.

I ordered a heavy duty mattress bag to protect it during transport.
Pick up in downtown Palo Alto, in the evenings between 7pm and 9pm.
